Not to be confused with the 1980s dance hit by New Order, this complicated romance tries to untangle the ties between two friends and the woman they both love. Taking the rap for his lover Eun-hee's crime, Keum-sook is sent to prison. But while he's incarcerated, she falls for his best friend, Doo-chan, and the two begin a passionate affair. Upon Keum-sook's release, he discovers their infidelity and subsequently crafts a plan to end his pain.
